[VFX Graph] Light and shadow information inherited by a translucent material at spawn remains constant and does not take into account the particle's orientation

-

How to reproduce:

  1. Import the attached package to HDRP project
  2. Open 'Scene' scene
  3.  [Optional] To understand this bizarre behavior, in Hierarchy, select NEW > ShadowCaster and turn on/turn off Cast Shadows in Lighting dropdown and pan Scene View camera around 
  4. Open Game View
  5. Observe that lighting information received at spawn time sticks with the particle thus areas that should be shadowed looks lit and vice versa. When orientation changes and we pan camera around I'd expect light/shadow information to be updated accordingly.

Notes:

- See attachments for visuals

- I've shared Slack conversation in the comment section, it contains a good comparison of particles vs plane from Julien. The bug was initially found in FPSSample.

  1. Resolution Note:

    The perceived issue was caused by the particles receiving shadows, unlike in the reference scene.
